JOHN R. DAVIS, OF CHICAGO, ILLINOIS.`

REFRIGERATOR.

SPECEICA'IJIOINT forming part of Letters Patent No. 518,096, dated Aprilk10, 1894.

Application filed November 24, 1893. Serial No. l91,861- (No model.)

To @ZZl whom t may concern.-

Be it known that I, JOHN R. DAVIS, a citizen of the United States,residing at Chicago, in the county of Cook, State of Illinois, have in.-vented certain new and useful Improvements in Refrigerators; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

This invention relates to improvements in refrigerators and has for itsobject to provide in compact form an automatic weighing mechanism incombination with the refrigerator case whereby the quantity of icewithin the ice box o1' receptacle will at any and all times beaccurately indicated.

It consists in a platform scale, an ice box supported on the platformscale and an automatic weighing device all arranged within the casing ofthe refrigerator and in other improvements all of which will behereinafter fully described.

In the drawings,-Figure lis a perspective View of a small refrigeratorconstructed according to my invention. Figs. 2 and 3 are verticallongitudinal sections formed on lines at right angles to each other.

A is a refrigerator which may be of any desired form. I have shown around casing but it will be readily seen that it may be made of anyform. It is provided with a door A through which the food or otherarticles are passed into the chamber A2.

The refrigerator is composed of the outer and inner casings A3 A3 withthe base B and the top C. The top is provided with a suitable openingthrough which the ice is passed, and is provided with a door or lid C.The top is securedin place by screws or bolts D which engage with lugs Don the inner side of the inner casing A4. The space between the casingsmay be packed in the ordinary way or may be left as a dead air space. Atone side, preferably the front side, a dead air space E is providedbetween the casings and nearthe top of the refrigerator. A narrow slot Eis formed through the inner casing near the bottom of the space E. Across bar F is placed within the refrigerator and in the presentstructure a -revolving shelf F as shown. A flat narrow ledge or supporta (annular in the present instance) is secured to the inner casing justabove the slot E, and is perforated with a drip opening a whichcommunicates with the drip chamber d2 arranged venient part of therefrigerator for instancel at the front just over the door A', I haveshown two drip chambers in the drawings, but only one of them isutilized. Immediately above the ring d I place the ice box or pan G andprovide it with drip spout which passes through the opening d into thedrip chamber a2. The ice box is less in dimension than the innerdimension of the refrigerator thereby providing a space for thenecessary circulation of the air. In case of derange- .ment of any ofthe working parts of the weighing mechanism the ice box will beprevented from falling by the ring a. A number of supports d areattached to the under side of the ice box and support the latter inplace on the weighing mechanism hereinafter described. v

g g are two bifurcated weighing levers the ends of the arms of which areheld in rings or loops g2 working looselyin eyes g3 secured in the ringa. The levers g g are coupled together at their apexes by a loop g4. Thelever g has extended from it the beam g5 which passes through the slot Einto the dead air chamber E.

The supports d of the ice box rest on the arms of the levers g g.

Within the dead air chamber E I place the weighing mechanism z'consisting of the rack bar la the lower end of which is connected to`the end of the beam g5, the pinion k' and the ICO ing is doneautomatically. Further it is so constructed that the waste by themelting of the ice will be indicated.

The ice pan or box is removable. In the refrigerator shown, by removingthe top the pan may be lifted out. This is a convenience sometimesneeded for purposes of cleaning or for repairs. In that class ofrefrigerators in which the top is hinged to the easing, the pan can belifted out at any time.

Having thus described my inventiomwhat I claim, and desire to secure byLetters Patent, is-

The combination in a refrigerator of a pro-
